I'm about to order a barrel for NRL hunter matches and I'm torn between the 6.5x47 Lapua or the 25 cal version.

Given the power factor requirements I'd have to send a 134 around 2840, or I could shoot a heavier 6.5 like a 144 lrht at 2650.

I guess what I'm really hung up on is whether or not a lighter 25 cal bullet going 2850 offers any advantage in terms of recoil or ballistics over a slow high bc 6.5?
 
I would check TNF and use whichever one has a higher TNF and still makes power factor.
